Initial analysis

The two-unit residential building at 3605 Irving Street in San Francisco's Outer Sunset neighborhood was constructed in 1945 and is currently owned by the Chau Family Trust. The two-story flats and duplex structure has undergone several significant modifications over its lifetime, with the most substantial work occurring in 2011 when unauthorized kitchen and bathroom remodeling on the top floor unit (Unit #307) led to a building violation, which was ultimately abated in February 2013. This renovation included electrical work for new lighting and receptacles, and plumbing upgrades for bathroom fixtures, costing approximately $15,000. The building has experienced maintenance issues over the years, most notably a significant plumbing problem reported in September 2021 involving sewage backup affecting various fixtures in the in-law unit, and a complaint in March 2014 regarding a possible illegal in-law unit with concerns about faulty gas lines, though these complaints are now inactive.

Earlier history of the building shows various maintenance work, including roofing projects in 1998 and stair/roof deck repairs in 1984, though the latter permit expired. A pattern of garbage and debris issues has emerged recently, with multiple reports of overflowing city garbage cans on the street from January 1 to January 11, 2025. A fire-related incident is recorded in the system, but it was limited to a malfunctioning smoke detector with no civilian injuries reported. The property's history suggests ongoing maintenance and compliance challenges, particularly regarding unauthorized modifications and plumbing systems, though many of these issues have been addressed through proper permitting or are no longer active. The building's age and history of plumbing-related problems may indicate potential infrastructure concerns that warrant attention.

Risk rating

How 3605 Irving St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
